The cheapest and perhaps the best method of running Matrix on a Macintosh computer is via the software package WineBottler.
Recently I obtained a Macintosh and have been testing various options for installing and running Matrix software. I have been able to exhaustively test the Wine software and so far I have not been able to fault it.
The Wine Software will run Matrix as though it was a native Mac application.
After installing WineBottler all you need to do is to download Matrix V6. You can ask WineBottler to install it and "hey presto" you have it!
If you wish to try out the demo version of Matrix V6 click the link in the right-hand menu panel.
Crossover is commercial software developed by CodeWeavers Inc to run Windows programs.
It uses WineBottler in a more intuitive way but it costs more to do this.
You can try Crossover if you wish as they have a 14 day trial. Download and install the trial then download the demo version of Matrix V6 and see how it goes. All the instructions for installing Crossover and installing any Windows software on your Mac are available on the Crossover website.
